Abstract
The deficiency of organ donors remains a barrier to kidney transplantation. Living donor kidney transplantation (LDKT) can overcome graft shortage, resulting in better outcomes. Many efforts are being made to expand the donor pool, such as hepatitis B surface antigen (HBsAg)-positive donors to negative recipients and anatomically complicated donor kidneys with size discrepancies. We report a case in which we overcame various problems in LDKT. The recipient was a 56-year-old, 106-kg, HBsAg negative male with diabetic nephropathy. The donor was a 63-year-old female, 56-kg, hepatitis B virus (HBV) carrier with dual renal arteries. Preoperative antiviral medication was provided to the donor for negative conversion of HBV-DNA. The recipient was given HBV vaccination (antihepatitis B antibody: 2.25-36.16 mIU/mL). Anti-HBV immunoglobulin was intraoperatively administered to prevent transmission. The donor and recipient had an absolute weight difference (50 kg). In addition, the donor's kidney had a main and an accessory artery in the upper pole, which were anastomosed to the recipient's right external iliac and inferior epigastric artery, respectively. Follow-up serum creatinine levels decreased. Doppler ultrasonography showed good vascular flow within the reference range of the resistive index. The recipient's follow-up HBV-DNA titer was negative with antiviral medication. We successfully performed LDKT from an HBV-positive donor to a negative recipient by perioperative antiviral treatment and overcame a significant size discrepancy and anatomic challenges by preserving even a small portion of the kidney graft.
